What we cover
Extensions for every project.
Single-storey extension
Rear, side, or wrap-around. The most common route to more living space without the complexity of a second storey.
Two-storey extension
Extra bedroom above, open-plan below. More space per square metre of footprint — better value when the foundations allow it.
Internal reconfiguration
No external build required. Move walls, open up kitchens, or reconfigure downstairs layouts to suit modern living.

Common questions
Frequently asked questions
Do I need planning permission for a house extension in Dorset?
Many single-storey rear extensions fall under Permitted Development rights and don't require a planning application. We assess your project and advise whether you need a full Householder Planning Application (£2,200) or a Certificate of Lawfulness (£1,500).
How much does it cost to get extension plans drawn up?
Our remote design discovery is a fixed £250 for 2-3 professional floor plan options. If you need a 3D laser scan for exact measurements, that's £650. Planning submissions start from £1,500. All pricing is fixed and transparent.
How long does it take to receive my extension plans?
We deliver your initial design options within 48 hours of receiving your photos or Rightmove link. If you upgrade to a site scan, the full measured drawings are delivered within a week of the visit.
What is a Certificate of Lawfulness?
A Certificate of Lawfulness confirms that your proposed extension falls within Permitted Development rights and doesn't need full planning permission. It provides legal proof that your build is lawful — useful for mortgage lenders and future buyers. We handle the full application for £1,500.
